There is an episode of Seinfeld, and I really can't remember what one this is from but it probably is from this season, where George goes to a cashier at a pharmacy and gives her a twenty and she says he only gave her a ten (no this is not the one with the lady from the restaurant on the horse). George protests and the lady calls a security guard and George is promply ejected from the store. He later tries to steal something in retribution to make up for the $10 he lost. Actually, I think this is an old episode. My point is, having worked in a pharmacy for several years now, that this is a totally unrealistic portrayal of what would happen in this situation and should not influence your views on the retail profession. If this actually occured (and it has) the manager would take the cashier's drawer, count it, and if it was off by $10 or close to ten dollars, give the man his ten dollars back. The point is, George would never be dismissed like that, the cashier could not have been so rude, and a guard would never eject the man from the store. In fact, the pharmacy would have gone out of its way to placate the man so as to preserve its reputation. CVS/Pharmacy (the largest interstate pharmacy/store chain owned by the Melville Corporation) would have responded to the situation in this way, as would Rite Aid, and F& M. I'm not terribly concerned by the episode except that I think that most people believe that is how retailers respond to those situations and thus they don't bring their problems up and this isn't even close to store reaction.
